Six degrees of separation theory is correct
The six (or seven) degrees of separation no longer appears to be a myth now it's been proven by Microsoft in a study of 30 billion text messages, but I guess the chaps at Facebook already know this. It's quite a thought that you can be connected anyone else on the planet so easily.
A US study of text messages suggests the theory that we are all linked six steps to anyone else may be right - though seven seems more accurate.
Microsoft researchers studied the addresses of 30bn text messages sent during a single month in 2006.
